nope. as far as i know, no question of statics came from any other book than ghori.
and cover dynamics first and then ode/pde and numerical methods and then tensors/vectors in the end and check if any Qs from ex 3 has come. i intend to solve the exercise but i have packed my key book.

Hi bro - Below is the link for Kryzsig book and manual.
https://www.dropbox.com/sh/oy35emljl...YSAjwDW0iUMcza ODEs tell me that concept of integration is more important than the ODEs themselves. Having good grip on integration techniques is very important - the little part is recognition of the type of ODE.

@ Roshnain. Which method have you reached? I am doing ODEs too.

Am done with the First Order ODEs. Will start Second order tomorrow. And yes- I saw those naughty questions there in the past paper - 1b of 2013 - and 1b of 2012. I am sure there must be something terribly wrong with that of 2012 as it cant be solved in any way. I think there must be a typo. For the 2013 - my conjecture is that there is a typo too.

Am using Kryszig - And Schaum series. I have the MGraw Hills book too but have not gone through it. Am just brushing up my previous understandings.
Did you look at the 2013 1B question?

2013 1b. replace dy/dx with dx/dy
remove "=0" from the end and eula! Bernoulli!

The removal of zero is obvious. But how can we replace dy/dx with dx/dy without actually manipulating the other terms in the equation. I tried to make it Bernauli of the type dx/dy + P(y)x = Q(y)x^3 but couldnt actually manipulate it that way. Can you share if you have solved.
Baqi, if you suggest a direct replacement of dy/dx with dx/dy, i dont think we can do it like that.

it is a typo na bhai. that is why replace dy/dx with dx/dy. let me solve it. there is no other way. and forgive me for asking this: are you my bro or my sis?
